ZOOM LENS AND IMAGING APPARATUS

摘要

A zoom lens is constituted essentially by six lens groups, in order from the object side to the image side: a first lens group having a positive refractive power; a second lens group having a negative refractive power; a third lens group having a positive refractive power; a fourth lens group having a positive refractive power; a fifth lens group having a negative refractive power; and a sixth lens group having a positive refractive power. The distances between all pairs of adjacent lens groups change when changing magnification from the wide angle end to the telephoto end, and Conditional Formula (1) below is satisfied:;−5

1. A zoom lens consisting of six lens groups, which are, in order from the object side to the image side:
a first lens group having a positive refractive power; a second lens group having a negative refractive power; a third lens group having a positive refractive power; a fourth lens group having a positive refractive power; a fifth lens group having a negative refractive power; and a sixth lens group having a positive refractive power; the distances between all pairs of adjacent lens groups changing when changing magnification from the wide angle end to the telephoto end; the distance between the third lens group and the fourth lens group being shortest at the wide angle end throughout the entire magnification range; and Conditional Formula (1) below being satisfied:
